I know it's ghetto ridged, but its only for temporary use. I used the windshield washer hose and connected to some type of adjustable valve and it sparys water onto the intercooler when you activate the washer lever.

Have u felt a difference with it yet?

legendr35

I just put it on, haven't used it yet. Going to tomorrow, when i start to heat soak

make sure to use clean water, you don't want to get anything oily or dirty on your belts or they might start to slip.

futurerexowner

Yeah I would be a little cautious of using anything that is going to end up going all the way through the IC. You might want to try something that evaporates very quickly, creating more cold... I would go with a liquid gas, not necesarily nitrogen but maybe CO2, or Oxygen. Also, you can buy that gum remover stuff for pretty cheap, although I dont think it is very pure and would steer clear if you can find something else.
Good Luck and let us know how it works,

i would like to use a misting system, but that kinda hard to make...i need to find proper soloniods, etc...but i'm just doing this to cure heat soak after a run

legendr35

what problems will spraying water on the IC?

jspecracer7

I've seen a similar setup with SR20DET's and this type of spraying system. Seems to work good for them. No ill side effects that I forsaw. 1Bad180SX had this on his car for awhile before going front mount, and had no problems.

Johnsrx7

Why not put them on the other side of the IC to spray out of the car. You will use this system when the IC is heat soaked at low speeds correct? Once you start moving at high speeds you don't need the spray.

I would turn it around so you are not spray the water into the engine and potentially shorting out an electrical wire or two.

Make something to seal up that big hole in the duct. Air will take the path of least resistance, in this case it's choice is to go through the IC or out a big gaping hole... which would you choose? Even duct tape is better than leaving it open like that.

Get a misting nozzle from McMaster-Carr for $3 and it would work much better. And seal up that gaping hole in the ductwork.

stop ghetto ragging it and get the n-cooler. works great and evaporate quickly too.

Since this has been such a big topic lately I have start to design some sort of ic spray system in which I am using CO2 to hopefully chill the intake charge air. Here is my idea:
You have a CO2 tank mounted in front of the ic on the passenger side (keep in mind that I have the m2 large smic). There is a way of blocking off CO2 from leaving the tank. Attached to the tank is a braided line that runs to a reservoir tank that also has a blocking system. Then there is a line running into the intake duct right before the intercooler itself. On the other side of the intercooler (driverside, after passing through the ic) there is a tempature gauge that measures the intake charge air temp. Once this temp falls below a certain set temp then the second valve opens allowing the CO2 in the reservoir tank to go into the ic and then it closes and the other valve opens refilling the reservoir tank. This way you do not have to worry about hitting a button or waiting too long after the ic is already heat soaked.
What do you all think of that idea? I am still working on it but that is the main goal.

Does the IC provide cool air for combustion, if so, then putting an inert gas in there is not a good idea.

Using 02 to cool down the IC is stupid IMHO. This is called converting your engine bay into a bomb. This would put you up for a Darwin award. There is enough electrical activity under the hood that I would not want to risk it.

Pure stream of 02 + spark = bad news.

ttpowerd

I have been contemplating this too. Like I said I am still just playing around with some ideas and some ways of preventing heatsoak.

rotorbrain

just use a fine mist nozzle or possibly alcohol.

PVerdieck, the idea here is to cool the intercooler fins. Nothing but charge air is passing inside the intercooler, this is just an external cooling aid. It would be like misting your radiator to make it more efficient, exact same concept.

What temp is CO2 when it is released?

ttpowerd

Not sure but I know from my paintball days that it is very very cold. I think it is below the freezing point because enough of it will start producing frost on any object. I'll check into it when I can.

I don't know how safe I would feel to have a pressurized tank in the front (hot) section of my car. Any words on this?

turp182

ttpowerd, I share your concern about pressurized gas in the engine comparment. Sounds to me like the rear compartments would be a great place to stick a pressureized canister compared to the engine. But then you have to run braided hose all thought the car.

Myself, I would just stick with water. It's cheap, safe, and more effective than not having a spray system.

ttpowerd

I would not be worried about the braided hoses but I am more worried about how to accomplish it if/when I choose to do so. You can always run the lines carefully under the car in well protected places or fab. a shield of some kind. That's when it gets into what size tank do you need...you need one big enough to fill the lines, however many feet it is from teh back tank to the intercooler, and still have enough to spray the ic. I'm still thinking about it though

edit* How do you know water is more effective than CO2? Until it is done wouldn't it be just pure guess and speculation? I would say that due to the temperature of CO2 and its gaseous state it would be like driving in the winter and really chill the air.
I would definately say that water is probably more efficient but not necessarily more effective.

Badog

Boiling point of CO2 is around -100F. Nitrous is about -30 colder.

When it hits the air it goes from liquid to gas, hence it boils.

Silver94

I have almost the exactly same set up on my car. I spary a mixture of 50% water and 50% rubbing alchool on my intercooler.

ttpowerd

How does it work? What sort of setup did you use? Thanks

RX7Elmo

you can buy denatured alchohol or rubbing alcohol for very cheap at your local orchards or paint shop. $5/gallon if i remember. Spraying that on the IC with water helps.

I can't really tell a big difference once I get my power fc next week I will see if it lowers my intake temp at all.
